Option to "Integrate with SmartObject" on InfoPath file missing
 

Diagnoses

Attempting to integrate K2 with a InfoPath form, however the "Integrate with SmartObject" option (when right clicking on the .xsn file) is missing. I've also attempted to integrate K2 using the SourceCode.Workflow.XSNSmartObjectIntegrator.exe utility, but get the following error after selecting the file:

The solution has not been opened. The following error occurred on opening. Value cannot be null. Parameter name: adapter

This functionality existed in 4.6.6 and I'm wondering if it's been replaced or broken with 4.6.10. Please let me know if you need any more information.
